Speed limiter device having automatic reversion function

Abstract

The invention belongs to the technical field of speed limiters, and particularly discloses a speed limiter device having an automatic reversion function. The speed limiter device comprises a speed limiter mounting seat and a speed limiter wheel, wherein centrifuging weights, a first spacing piece, a brake block and a brake wheel are mounted on the speed limiter mounting seat; a first transmissiongear is hinged to one end of the brake block; a second transmission gear is mounted on the speed limiter wheel in the direction parallel to the axial direction; a bevel part is arranged on the upper end surface of the second transmission gear; the second transmission gear and the first transmission gear are mutually meshed; a first fixing piece is arranged on the speed limiter wheel; a bevel button which can be in line contact with the bevel part of the second transmission gear is arranged on the first fixing piece; a touch assembly is arranged on the speed limiter mounting seat; and a secondcompression spring is arranged between the bottom of the first fixing piece and the upper end surface of the second transmission gear. According to the speed limiter device disclosed by the invention,accidents and faults generated during elevator operation can be effectively avoided, so that the elevator car during operation can stop in time, and reversion is convenient; and the speed limiter device is safe and reliable, manual operation is not needed, and the speed limiter device can be widely suitable for an elevator without a machine room.

Description

technical field [0001] The invention belongs to the technical field of speed limiters for elevators, and in particular relates to a speed limiter device with an automatic recovery function. Background technique [0002] Compared with machine-room elevators, machine-room-less elevators move the control cabinet, traction machine, speed limiter, etc. in the original machine room to the top of the elevator shaft or the side of the shaft, thus canceling the traditional machine room and maintaining the original performance. Miniaturization under the premise to meet customers' special requirements for height and roof. [0003] For elevators, the speed limiter is one of the safety control components and is a very effective emergency brake device for the elevator car. When the safety protection device does not work, the speed limiter and the safety gear will have a linkage action, which will stop the running elevator car. [0004] In the prior art, the speed limiter of the existing...

Problems solved by technology

[0004] In the existing technology, the speed limiter of the existing elevator usually uses manual operation or motor action to realize the reset action of the speed limiter, but the machine room-less elevator cannot be operated by manpower, and the cost of the motor action is high

Moreover, the existing small machine room ladder speed limiter needs to put the hand into the speed limiter to perform the reset operation, which poses a certain threat to personal safety.
